The suspects in the death of a man whose remains were found in four bags in Laurel, Maryland, Sunday were the victim's roommates, according to Prince George's County Police.

Police arrested one roommate, 32-year-old Santos Leonel Mejia-Yanes, and charged him with first- and second-degree murder. They have a warrant charging 34-year-old Bayron Cruz-Vargas with first-degree murder, first-degree assault and other charges.

Mejia-Yanes and Cruz-Vargas lived with 28-year-old Jacinto Perez in an apartment on Finsbury Court, police said. An argument became physical and violent, resulting in Perez's death.

The suspects dismembered Perez's body and discarded his remains in various places throughout the apartment complex, police said.

When officers arrived at the scene Sunday morning, they found bags containing body parts. Remains were found in at least three locations and at least four bags, Maj. Cesar Pacheco said. Remains were found in and outside of dumpsters.

Wednesday night police found Mejia-Yanes, who admitted he was involved, Pacheco said. He is being held without bond pending his trial.
